To all whom it may concern:-

Be it known thet I, GEORGE Visnmerorz BENNUM, citizen of the United siding at Georgetown, in the county of Sue sex and State of Delaware, have invented certain new and useful Improvements in Fountain-Pens, of which the following is e specification. i

The invention relates in general to fountein pens and particularly to a means for ositively controlling-the flow of ink to the eeding device and to e. specific construction of the letter.

The main object of the inve'ntionis the production of e. pen of the class described which embreoes meens,'irrespeotive of the position of the pen, for preventing accidental/flow of ink to the Writing point and consequent leeltege and soiling of the hands and of the user.

Anot ier object is the provisionof e nonclogging feed device acle ted to insure unimpeded initiel flow of in endto r'neintein e uniform delivery to the pen point and .25 which is especially adapted to coect with the flow-controlling means.

Another object is to provide an ink-tight connection between the body portion of the Writin point and the nipple.

Wit these primary objects in; the invention will now be described in the following specification taken in connection with the accompanying. drawings end then ,more zrticelerly pointed out in the claims.

In t e drawings, Figure 1 is a. perspective of my invention. Fig. 2 is e top pier). of the feed device. Fig. 3 is e vertical longitudinal seetion oi' tlie feed device writing point, and

flow-controlling means, illustrating the petite 4o edgusted to prevent flow of Fig. is erspeotive of he iiow-oontrollum ineen 'ig. 5 is e trensversesection on line Fig.9. Fig. ii is e transverse sect. u -e'.:z; of Fig. 3. Fi 7 is a. horizo t l tutlinel centrelseetion ofthe nipple. Referrhig-now to the drewings,'wherein like reference numerals refer tolike parts throughout the several views, 1 denotes the handle reservoirof the pen, constructed of any desired or usual type. I

2 indicates the nipple, reniovebly attacheri to the handle by usual threaded connection and comprises a tube of idesirecl length and external ooniiguretio videil for :1 portion of its leno'th the fort. er er- 5 .J Ll with here 3 end with smaller bore 4 for Specification of Letters 399" the wri I on the 5i nee-r ee. emit-our, sirnuit one g-po these grooves i their outer end to reservoir 10, evonii 12 and in time. 1. of the body 0 site said oi.

e en cl devi i body andfornis a perfectly ink-tight connection, thus preventing flow'of ink along portions where not desired, it being under stood that the terminate longitudinal edges of said body portion of the peni po'int andofi set 13- contact throu hout their'le tli'. That portion of the feed device beyond '0 set 13 is of such dimensions as to'snu ly fit" within bore 4 of the nipple and'be em raced;

by the walls thereof, the rear ends of the en point'body and offset abutting the shou der 4 which thus properly limits the longitudinal movement of the feed device when it is being assembled with the nipple.

14 denotes .the cut-off for controlling the flow of ink to the feed device and comprises a cylindrical shaft 15, preferably thou h not necessarily, of equal length'with t e body section of the feed device and adapted for partial -rotation within the bore thereof, said shaft being bored for a 'ortion of its length at one end and provided at approximately the forward end of said bore with an aperture 16 openin '-into said bored portion, and at the other en with an adjusting-lug l7, abutting, when the several parts. are in operative position, the forward edge of offset 13. The apertures 12 and 16 are the same distance fromthe assembled adjacent ends of the feed device and cut-off respectivel and can, as obvious, through rota tion of sliaft 15 b manipulation of adjusting-lug 17, be ma e to aline and permit flow of'ink' to the feed groo'ves aperture 16 being insuch 'cricuinferential relation to said lug as to insure registry ,of the'two apertures when the lug is turned to extend in one direction approximately transverse the lower face ofthe nib section of the feed device and to 40 position diametrically opposite to aperture 12 when the lug is turned to extend in the opposite direction and same relative position to said feed device, against/which, whenin either position, the lug will abut at the limit of its movement and rest closely contiguous and out of the way. t

From the foregoing it will be see that I have provided a fountain pen embracing means for preventing the leakage common 50 topens of this class, said means being positive and efficient in action, readily and easily manipulated by the user and, when adjusted to either permit or prevent flow of the writing fiuid,'so.positioned as to be entirely removed fromv interference with the users fingers, the pen also embracing a feed device especially adapted for use with the flow-controlling means and insuring aconstant' and l uniform supply of ink to the writing point or a supply at an increased rate of flow, as

desired and which provides an unimpeded initial flow without other manipulation than adjustment of the cut-off lug. It will also be obvious that the feed device formed with the offset on its forward end of such thickness as to completely fill, in conjunction with the body portion of the writing point, made of equal thickness, the bore 3 of the nipple, in- #sures a perfectlytight connection between the feed device, writing point, and nipple. Having thus described my invention, what I claim as'new and desire to secure by Letters Patent, is 1 1. A fountain pen comprising an ink reservoir, a feed device adapted to receive a supply of ink therefrom, a centrally-bored shaft within the feed device provided with means for'controlling the supply of ink thereto, and a lug formed integral with said shaft and positioned contiguous said feed device and adapted for partial rotation, said lug abutting, at the limits of its rotation, the feed device for adjusting the supply-controlling means. I I I 2. A fountain pen comprising an ink reservoir, a feed device adapted to receive a supply of ink therefrom and formed with an inlet aperture, a centrally-bored shaft within the feed device provided with means for controllin the supply of ink thereto, and 8. lug, forrne integral with said shaft, located contiguous the feed device and adapted for limited rotation and, at the opposite limits thereof, to abut said feed device and aline and disaline said apertures. I 95 3. A fountain pen comprising an ink reservoir, a feed device adapted to receive a supply of ink therefrom and provided with a plurality of feed grooves deepened near their outer ends to form a supplemental reservoir, a shaft rotatable within the feed device and provided with means for controlling the supply of ink thereto, and means located beneath said feed device for adjusting the supply-controlling means.-

' 4. A fountain pen comprising an ink reservoir, a nipple formed with an offset to receive a pen point body, a feed device connected to the nipple and adapted to receive a supply of ink from the reservoir, a pen point, a centrallybored shaft within the feed device adapted for oscillation and mea'nslocated beneath the per point body for controlling the flow of in 2 In testimonylwhereof I hereby affix my 115 "signature, in presence of two witnesses.
